MasterPark Armory Demolition


Location: Anchorage, Alaska
Type of Project: Industrial; Demolition
Project Duration: June-July 2013
Contractor Type: Subcontractor

Hazardous Materials Removed: Asbestos
Quantity Removed: 3,150 CY
Scope of Work: Established traffic control plan and haul routes to eliminate congestion and improve safety measures. Erected temporary fencing and appropriate signage to demarcate work areas. Coordinated all utility disconnects to include communication, electrical, sewer, storm, and water with the general contractor, private trades, and City departments. Structure was demolished from south to north to allow the civil subcontractor to begin excavation for new underground utilities. Demolition was confined to the building footprint to accommodate hauling and excavation activities. Dust control was extremely important. We had to assure building debris did not blow into the active taxiway at Lake Hood Seaplane Base. General debris was loaded and hauled to the local landfill. Concrete and asphalt pavement was separated and recycled on-site utilizing a mobile crusher. Recycled aggregate was crushed to 3-inch minus and utilized as backfill for the new construction. Steel, rebar, and other non-ferrous metals were recycled. Site was rough graded. No landscaping was required as the site was transformed into the new airpark. Coordination and phasing were key elements in order to maintain the aggressive project schedule. The project was an overall success with zero accidents and on schedule.
Work Subcontracted: Air Monitoring, Crushing
